SHINGLE.

Application led. April 9,

This invention relates to strip shingles carrying a plurality of vbuttsand lpreferably constructed from roofing feltor material of similarnature covered with a mineralcoating of some finely divided hardsubstance,

such as stone or slate.

It is an object ot the invention to provide rooting materialcon'iprising two different strips or shingles cut out in pairs from aroll or sheet ot material crosswise thereof which will, when laid, forma thatched roof 'having a series of undulating edges irregularlyarranged.

A further object ofy the invention is to cut each of said two diierentshingles so that the longitudinal edges thereof will all be differentlyshaped, although the longitudinal edges on one shingle will becomplenientarily shaped with the respective longitudmal edges on thesecond shingle whereby the shingles may be cut out in pairs from a rollor sheet ot' material crosswise thereof withoutl waste. By forming cachlongitudinal edge ot the two designs of shingles dlttercntly, variousirregular and tortuous lines may be formed in a roof laid with saldshingles and either of the longitudinal edges ot each shingle may bedisposed downwardly as desired. In other words, both of the shingles orunits are reversible edge for edge.

These and other objects of. the invention will be apparent from thefollowing description made in connection with the accompanying drawingswherein like characters refer to similar parts throughout the severalviews, and in which y Fig. 1 is a plan view ot' one of the pair otstrips or shingles embodying the invention,

Fig. 2 is a similar View of the other stripv or shingle embodying theinvention.

Fig. 3 is a plan view of a portion of a sheet of material cutout to formthe pairs of shingles or strips, and

Fig. 4 is a plan view of a' plurality of each of said shingles arrangedand laid to cover a roof and present a thatched appearance.

The shingles are preferably constructed from a foundation-sheet of woolfelt or other similar material with a coatiner of some selfhardeningmaterial, such as pitch or asphalt on one surface thereof and with a.layer of finely divided hard material, such as slate or stone thrustthrough the coating and embedded therein.

In the drawings two different and distinct shingles are shown indicatedby the letters A and B respectively, cut in pairs crosswise of a sheetor roll of material. Shingle A illustrated in Fig. v1 has itslongitudinal sides 1 and 2 cut on different non-parallel tortuous lines.The ends 3 ot' shingle A are parallel to each other and perpendicular tothe longitudinal center line of the shingle.

Shingle or section B (see Fig. 2) has its longitudinal edges cut onnon-parallel tortuous lines 4 and 5, t-he edge 4 being complementarilyformed with edge 2 of shingle A and the edge 5 ot' shingle B beingcomplementarily formed with edge 1 of shingle A. Thus it will be seenthat the combined width of shingles A and B will be equal through allpoints across the width of the roll from which said shingles are cut.

Fig. 3 illustrates the manner in which the shingles' are cut erosswisefrom the roll or sheet. Thedotted lines indicate the edges ot the sheetand it will be obvious that there will be only a very small amount ofwaste in cutting the first shingle from the roll indicated by the cutout corner portions and y respectively. A plurality, shown as three inthe drawings, of slots 6 are eut intersecting the complementary edges ofa pair of. shingles and parallel with the ends of the sheet or roll.These slots. it will be seen, have their ends aligned at right angles tothe longitudinal edges of the roll and they extend at various depthsinto the separate shingles, thereby forming four butts on eachlongitudinal edge of each shingle. In shingle A the but-ts on the upperlongitudinal edge are numbered 7, 8. 9 and 10, while the butts on thelower longitudinal edge are numbered from left to right 11. 12, 13 and14. The butts formed on the upper longitudinal edge of shingle B arenumbered 15, 16,17 and 18 respectively and the butts on the lower edgeare numbered. 19, 20, 21 and 22 respectively. Notched recesses z are cutout from the outer edges of the ends ot each shingle adapted to formslots similar in shape to the slots 6 when two shingles are abutted endfor end as shown in Fig. 4. Notched recesses e also torm'nail'ingflanges at the ends of the shingles.

It will be seen that each butt formed on the two shingles is differentlyshaped from every other butt on the two shingles and will simulate agreat Variety of separate shingles 1w or pieces of slate when the roofis laid. Every butt, however, has a complementary shaped butt on theother shingle of the pair.

In laying the shingles upon a roof, parallel horizontally extendinglines are usually drawn on the roof on which the nailing ianges atl theends of the shingles A and may be gauged.- The shingles A and B may bethen laid on with the desired longitudinal edge downward, the nailingflanges of one shingle abutting the nailing fianges of another shinglelaid along the side thereof. The shingles are preferably broken on thethird when the succeeding layers are laid but may of course be broken onthe half if desired. However, by breaking on the third it will be 0bvious that every part of the roof is covered with two layers of solidmaterial there above in spite of the slots 6. The beauty of the designobtained by laying the shingles islargely a matter of the skill of theroof layer in quickly picking the proper shingle A or B and turning t-helongitudinal edge downward to obtain -the effect of a series ofundulating edges arranged in non-parallel relation and almost coincidingin some points while spaced farther apart at other points. l

It is of course apparent that while curved lines have been shown asforming the longitudinal edges of the separate shingles, the points ofthe several butts may be connected by straight lines to form irregularand tortuous longitudinal edges all within the scope of this invention.Curved lines, however,

" give a slightly more pleasing appearance.

It is of course understood that I am not.

limited to the use of four butts for eachshintgle or strip, but that agreater or less number may be employed as desired and that variouscurves or tortuously extending lines may be employed to cut the longituinal edges of the shingles. It will of course always be necessary, ifthe shingles are to be cut from a sheet or roll without waste, to havethe edges l and 2 of shingle A complementary with the edges 4 and 5 ofshingle B.

It will be apparent that the amount of waste in the sheet or roll incutting my shingles is extremely small, being only the small cornerportions left in starting to cut the roll and that left at the end ofthe roll and the amount cut out for the slots 6 and notched recesses .eforming the several butts.

What is claimed is:

1. Roofing material for thatched roofs comprising two shingle strips cutfrom a sheet of material forming a four-sided figure having two oppositestraight and parallel sides, said strips being cut transversely so thatthey have their remote sides irregularly curved and substantiallyparallel and the contiguous sides so cut that the sides of each stripadj acent one end are oppositely curved and said sides adjacent itsother end are similarly curved and substantially parallel theopposite-curved sides of each sheet eing nonsymmetrical about any axislocated therebetween. l

2. Roofing material for thatched roofs including two shingle strips cutfrom a sheet of material comprising a four-sided gure with two straightparallel sides, the other pair of opposite sides being curved andsubstantially parallel and the cut forming the contiguous sides being inthe form of an irregular curve so that said contiguous sides arecomplementa] and the opposite curved sides of each strip arenon-symmetrical about any axis located therebetween.

In testimony whereof I aflix my signature.
